Iwaki MD Water Pump (Japanese Motor)
Information

Magnetic water pumps. Magnetic driven. Sealess pumps for use on fresh or saltwater aquariums. Low heat exchange and quiet in operation. Highly durable design. WMD pumps have American Made Motors. MD pumps have Japanese Made Motors. RLT pumps are for pressure applications. RLXT pumps are for circulation and wet/dry return.

Iwaki Walchem magnetic drive pumps will run longer, quieter and cooler than any traditional mag drive. Extraordinarily high efficiencies make WMD & MD the clear choice in almost every process, recirculation or transfer application.

Precision TolerancesPumps can be supplied with alumina ceramic or SiC spindles, bored, turned and highly polished. This precision machined spindle forms the center of the driven magnet. Substantially reduced hydraulic noise is a major feature of all WMD/MD impellers. Great pains are taken in the molding/finishing process to eliminate tangential misalignment.

Motor matchingOffering more standard motor/pump configurations than other manufacturers offer for tailored pump applications. Premium, high efficiency motors are used throughout the line. Totally enclosed, permanent split capacitor motors are compact, cool and economical. Tolerance to voltage variation without overheating and 50/60 Hz operation allow the product to be used in a worldwide market.

Do NOT send a pump back to Iwaki without an RGA number. Please contact us for any assistance you may need in this unlikely situation.

Comments:Very nice pump. It is powerful, and moves the water quickly. Its been running my tank since May now. I'm very happy with it, and the only complaint I have is that it seems to heat the water up. Not sure how that is happening, but I have never had to use a chiller until now. I'm hoping the chiller is not going to be a year round necessity.
The pump seems quiet as the reviews say. I paid a premium to get this model, and it appears to be a good choice. The external mounting frees up so much more space inside the sump.

Comments:replaced my gen-x pump with the md40 pump has slight hum, much quieter than previous pump. my md20 has been running for the past 12 years so if that is any indication of super pumps then no complaints.

Comments:Great pump, incredibly quiet and plenty strong to run my ETSS Skimmer which was recommended to run with the MD40. Only draw back is it does get very hot, but I'll take the heat over noise any day. I also purchased the MDX40 which works great but because of the fan it is a little noisy!! All in all you can't beat these pumps, well worth the money!!

Comments:There probably isn't a need to review Iwaki MD pumps. They've been around a long time and everyone knows they are well built. I have the 30RLT. The 20s and 30s don't have fans, so they run hot to the touch, but much quieter than the 40s and up. Pressure rated and likely to run unnoticed for years to come, it's a great pump. I also like knowing that replacement parts are easily found should I need them.

Comments:The Iwaki MD70 pump is a good quality and well designed pump, and circulates water quite well within the aquarium. It is however a bit on the loud side, so if you are looking for a quiet pump I would probably choose another. If you are wanting this pump to work with a large canister filter, it will certainly do the job with ease and can of course handle back pressure well.
It has performed flawless for me thus far and I would certainly recommend this pump to anyone who wants quality & dependability!

Amazing reliability!

Comments:I own an Iwaki MD-20RLXT pump that has been running my 90 gal tank for 26 yrs. I am debating on whether to rebuild it with a new impeller, front and back case, and o-ring. Parts and shipping total is 134.79.
I have been very happy with this pump and calculated that it has performed at least 43046640000 revolutions. That’s over 43 BILLION revolutions!
Should I go ahead and buy a new pump for $60.90 more? I think I just answered my own question!

Comments:Fan rubs on housing during start up. Sounds like something is stuck in fan, very loud then stops clanging when at full speed. Overall pump runs loud when in use compaired to the little giants. Time will tell on the reliability.

Comments:I am another one of the happy hobbyist with my Iwaki MD-30 RT return pump. My biggest problem prior to installing this exterior pump was heat and very little space in the sump for another pump, Iwaki solved that problem expertly. I've been running this pump for the past several years with no issue. Their is a constant low hum that I no longer pay any attention to.
This is a very good investment.
